So to answer the original question:
- Batman would identify with Arya because he is Arya.
- Wonder Woman I think would identify with Catelyn, Brienne, and Sansa and would be very disappointed in a lot of the fandom.
- Aquaman…maybe Stannis, because of the responsibilities of kingship and the naval connection.
- Hal Jordan is definitely a Jaime fan – arrogance mixed with ability.
- I think Martian Manhunter would probably feel some kinship with Bran Stark or Brynden Rivers.
- Barry Allen…probably Ned Stark? He’s a hard one.
